HESI RN Exit Exam 2024 Quizlet

Correct Answer: B

Rationale: Before hemodialysis in a client with end-stage renal disease (ESRD), monitoring serum potassium closely is crucial. ESRD patients are at risk of hyperkalemia, which can lead to severe cardiac complications. Checking serum potassium levels helps in assessing and managing this electrolyte imbalance. Serum creatinine (Choice A) is a marker of kidney function but is not the most critical value to monitor before hemodialysis. Serum sodium (Choice C) may be affected in renal disease, but potassium is a more crucial electrolyte to monitor. Hemoglobin (Choice D) is essential for assessing anemia in ESRD but is not the primary focus before hemodialysis.

Correct Answer: D

Rationale: Elevating the head of the bed to 45 degrees is crucial for clients receiving enteral feedings via a nasogastric tube to prevent aspiration. Aspiration can lead to serious complications such as pneumonia. Auscultating the client's lungs for breath sounds (choice A) is important but not as urgent as preventing aspiration. Checking the client's blood glucose level (choice B) and monitoring bowel sounds (choice C) are also essential aspects of care for a client receiving enteral feedings, but they do not take precedence over preventing aspiration.

Correct Answer: C

Rationale: The correct answer is C: Liver function tests. Methotrexate can cause hepatotoxicity, making it essential to closely monitor liver function tests in clients receiving this medication. Monitoring white blood cell count, hemoglobin, or platelet count is not specifically required for methotrexate therapy and would not provide relevant information regarding potential adverse effects of the medication.

Correct Answer: A

Rationale: The correct answer is A: Decreased abdominal girth. In a client with cirrhosis of the liver, a LeVeen shunt is used to treat ascites, which is the accumulation of fluid in the peritoneal cavity. A decrease in abdominal girth indicates that the shunt is effectively draining the ascitic fluid, relieving the client's abdominal distension. Choice B, increased blood pressure, is incorrect as a LeVeen shunt is not expected to impact blood pressure. Choice C, clear breath sounds, is unrelated to the effectiveness of a LeVeen shunt in managing ascites. Choice D, decreased serum albumin, is also not a direct indicator of the shunt's effectiveness in draining ascitic fluid.

Correct Answer: A

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to serious cardiac arrhythmias, especially during hemodialysis. Serum calcium, serum creatinine, and white blood cell count, while important, do not pose immediate life-threatening risks like hyperkalemia.
